As others have said, practice, practice, practice. Also, if you have a Orvis store in the area, you may want to check with them. I took a FREE class from them, which went over basic casting, and to be honest, it was really helpful. Its called something like "Fly Fishing 101", and then they also have a 201 where they take you on the water (okay, a pond). Regardless, its worth checking out.
I also took a free fly tying class there which went over basics.
